Struggling with AWS Certified Cloud Practitioner CLF-C02 exam questions? Learn what elasticity in the AWS cloud entails and how it enables dynamic scaling of resources to meet fluctuating demands. Elasticity in the AWS cloud refers to the ability to dynamically adjust computing resources—scaling them up or down based on real-time demand. This concept ensures optimal performance and cost efficiency by provisioning resources as needed and releasing them when they are no longer required.

Question
Elasticity in the AWS cloud refers to which of the following? (Select TWO.)
A. How quickly an Amazon EC2 instance can be restarted
B. The ability to scale resources as demand changes
C. The maximum amount of RAM an Amazon EC2 instance can use
D. The pay-for-what-you-use billing model
E. How easily resources can be obtained when needed
Answer
B. The ability to scale resources as demand changes
E. How easily resources can be obtained when needed
Explanation
Elasticity in the AWS cloud refers to the ability to acquire resources as you need them and release resources when you no longer need them. In the cloud, you want to do this automatically. This means that you can scale resources as demand changes and can easily obtain resources when they are needed.
B. The ability to scale resources as demand changes
Elasticity is a core feature of cloud computing, allowing systems to automatically expand or contract resources in response to workload fluctuations. For example, during peak traffic, additional instances can be provisioned, and when demand subsides, excess instances are terminated. This ensures efficient resource utilization and cost savings.
E. How easily resources can be obtained when needed
Elasticity also emphasizes the ease with which resources can be acquired or released on-demand. This process is often automated through tools like AWS Auto Scaling, enabling rapid adjustments without manual intervention.
Why Other Options Are Incorrect
A. How quickly an Amazon EC2 instance can be restarted; This pertains to instance availability or recovery time rather than elasticity, which focuses on scaling capabilities.
C. The maximum amount of RAM an Amazon EC2 instance can use; This relates to resource capacity limits (vertical scaling) but does not capture the dynamic scaling aspect of elasticity.
D. The pay-for-what-you-use billing model; While related to cost efficiency in cloud computing, this describes AWS’s pricing model rather than the concept of elasticity itself.
Key Takeaways
Elasticity ensures that AWS environments can handle varying workloads efficiently by dynamically scaling resources up or down as needed. This feature is critical for maintaining performance during demand spikes while minimizing costs during periods of low activity.
